FDA clears rotavirus vaccines

Posted May 14 2010 12:00am

The US Food and Drug Administration has updated its recommendations on both Rotarix and RotaTeq, vaccines for the prevention of rotavirus disease in infants:

Based on careful evaluation of a variety of scientific information, FDA has determined it is appropriate for clinicians and health care professionals to resume the use of Rotarix and to continue the use of RotaTeq.

In making its recommendation, the FDA considered the strong safety records of both vaccines, including clinical trials in tens of thousands of individuals and the use of the vaccines in millions of recipients. There is no evidence that either porcine circovirus type 1 or type 2 poses a safety risk to humans, and neither virus is known to infect humans or cause disease.

The FDA also noted that the benefits of the rotavirus vaccines are considerable and outweigh the small theoretical risk of the viral contaminant.

The product labels will be updated to reflect the fact that the vaccine contains a PCV contaminant. In addition, GlaxoSmithKline will rederive Rotarix so that it does not contain PCV. Merck has not yet made a decision about whether they should produce a PCV-free rotavirus vaccine. But if my suggestion carries any weight at Merck (I know it does not), they should not hesitate to follow GlaxoSmithKline’s lead.
